Currently, this bot just subtracts yesterday’s subscriber count from today’s, and give a percentage difference.

Current Algo: percentage difference in subscribers, averaged over the past 7 days. Where it’s showing less than 7 days, it’s because I don’t yet have the data (mostly because this bot hasn’t run for 7 days yet, but also because either it’s a new community, or because I had to fudge things a bit in the first few days by excluding communities with less 100 subscribers)

Please use this post if you’d like share better ideas of what constitutes “trending”, and if you have any preferences for how the posts are displayed. Thanks.
